Enabling or Disabling
a Snoop Filter
A snoop filter does not take effect until you enable it. To enable or disable
a snoop filter, use the following command:
set
snoop
{
filter-name
|
all
}
mode
{
enable
|
disable
}
The filter operates until you manually disable it.
The filter mode is retained even if you disable and reenable the radio, or
restart the MAP or the WX switch. Once the filter is enabled, you must
use the
disable
option to disable it.
The following command enables snoop filter
snoop1:
WX#
set snoop snoop1 mode enable
success: filter 'snoop1' enabled

The MAP collects statistics for packets that match the enabled snoop
filters mapped to its radios. The MAP retains statistics for a snoop filter
until the filter is changed or disabled. The MAP then clears the statistics.
To display statistics for packets matching a snoop filter, use the following
command:
display
snoop
stats
[
filter-name
[
apnumber
[
radio
{

|

}]]]
The following command shows statistics for snoop filter
snoop1
:
